Effect of <i>alsSD</i> and <i>sarA</i> mutations on biofilm formation.

<p>Biofilm formation was assessed using the microtiter plate assay. Results represent the mean and standard deviation of 24 replicates. Strain designations are the same as those in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0003361#pone-0003361-g001" target="_blank">Figs. 1</a>–<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0003361#pone-0003361-g002" target="_blank"></a><a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0003361#pone-0003361-g003" target="_blank">3</a> with the addition of the <i>sarA/alsSD</i> double mutant (UAMS-1300).
